Automobile rear axle housing three-face milling method

Abstract

The invention discloses an automobile rear axle housing three-face milling method. An axle housing body is included, the axle housing body comprises two sub-axle housings with the same shape, each sub-axle housing comprises a semi-circular axle body and axle arms symmetrically arranged on the left side and the right side of the axle body, and in the machining process, the middle of the axle housing body is positioned through a positioning device; the axle housing body is fixed at the axle arm positions on the left side and the right side through a pressing device, then the axle housing body is machined through movable cutter heads and a movable cutter disc at the same time, the movable cutter heads machine end holes and outer circular faces on the left side and the right side of the axle housing body, and the movable cutter disc machines the rear end faces of the two sub-axle housing on the rear side of the axle housing body at the same time; and through one-time clamping and simultaneous machining of the two movable cutter heads and the movable cutter disc, machining errors caused by multiple times of clamping of a workpiece in the vertical milling machining process are avoided, the concentricity of the two ends of the axle housing and the parallelism of the two end faces and the center line of the axle housing are guaranteed, procedures are reduced, tool equipment investment is reduced, and operation is simple and easy.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a three-side milling method for an automobile rear axle housing. Background technique [0002] The rear axle housing of the automobile is the basic part for installing the main reducer, differential, half shaft, wheel hub and suspension. Its main function is to support and protect the main reducer, differential and half shaft. One of the main components of the driving system, the drive axle housing should have sufficient strength and rigidity, low mass, and facilitate the disassembly and adjustment of the final drive. [0003] The rear axle housing is generally assembled from two sub-axle housings of the same shape. In the prior art, the two sub-axle housings are generally processed separately by end milling tooling. During this process, multiple clampings lead to machining The accuracy is difficult to guarantee, the investment in tooling equipment is high, and the...

[0003] The rear axle housing is generally assembled from two sub-axle housings of the same shape. In the prior art, the two sub-axle housings are generally processed separately by end milling tooling. During this process, multiple clampings lead to machining The accuracy is difficult to guarantee, the investment in tooling equipment is high, and the operation is very cumbersome
